What are the amps and volts for each hub?

Geoffrey,Although I have not measured them to be able to give you exact #'s I can tell you this. I am running a Yeti USB powered Mic, I Lacie 1TB drive and a My Book 1.5 TB Drive along with 2 Pioneer CDJ's (not powered through the device and I have not had any issues with my laptop seeing all of the devices. I would recommend it.

Sorry, I have no idea. Does the paperwork not state the capacities and capabilities...

For my application I just used a power supply set to 5v, but VBUS will power it just fine as one of my coworkers did with the same amp.

The hub overall is limited to 2A (2000mA). 3 of the ports are standard USB 2.0 500mA and are only powered when the host computer is on. One of the ports is marked as a "fast charging port" with 2A and available when a USB host is disconnected, though the specs state that this delivers only 500mA when a USB host is connected. I haven't measured this with a multimeter but based on what I've seen using the fast charging port to power a RaspberryPi (which is also the USB host) I believe the charging port is not limited below 2A when a host system is connected, but instead, all four ports are limited to the 2A maximum with the other 3 ports limited to 500mA each.

The product images show that this outputs 4 amps max. I don't own this product, but my guess is that each port is 1 amp.

I have no idea of voltage or amps...I have yet to use these items.Sorry I couldn't help more

I'm not sure about the amp numbers, but I'm using the hub with 2 USB3 portable drives, 1 USB2 Ethernet, USB keyboard/mouse, and USB/serial port, sometime plus more peripherals at the same time, without any problem.

I'm not sure, as I only have a USB 2.0 hub... I dont see why not. Still 5 volts I believe and receiving I.R. Is probably low voltage. G.L.

The hub can be powered by the AC adapter and or USB. I have one and I use it to dj. It is nice because if my computer looses power my controllers stay on because the hub is plugged directly into the wall. Don't get the USB 1.0 version I have it and it is terible. I went back and bought the 3.0 and it works great. I run a USB powered light of it so the on off switches are nice. Hope this helps.

The standard is 500mA for USB 2.0 and 900mA for USB 3.0. Do the math, and you'll see that the power supply doesn't cut it for 24 USB 2.0 and 4 USB 3.0 ports. 24 x 500mA = 12A 4 x 900mA = 3.6A The power supply would need to be 15.6A at 5V. Since the power supply is only 4A at 5V, you're only going to be able to power four USB 3.0 devices (900mA x 4 = 3.6A) OR eight USB 2.0 devices (500mA x 8 = 4A). Perhaps Manhattan should do what Anker does and use a 12V adapter and whatever they do to undervolt/cut down their USB 3.0 9-port hub to 5V per port (that thing comes with a 12V, 5A power adapter! The brick is almost as big as most laptop power bricks!) Using the formula of Volts x Amps = Watts (5V x 15.6A = 78W), we can conclude that at 12V, only 6.5A would be needed (12V x 6.5A = 78W). It's a shame, though, as a 28-port USB hub is cool as all hell, but in practice, it doesn't work right unless you're using all self-powered devices (devices that have their own power adapters).

There are two output ports. One outputs 2.1 amps and the other outputs 1.0 amps.

To answer your question yes is port supplies the 2 amps. Each USB port is dedicated. Unlike a hub that would split power. I had two iPads connect as well as one iPad and one iPhone and it worked perfectly

Sorry 15 should be 15AMPs and 123 watts should be 145 watts.My typing stinks

Hi Sheena: Jeffrey beat me to it. The only caution you want to take is to not treat this a 4 ports each capable of 15 Amps.With best regards

This hub does not include its own power supply so the *total* current it can supply among all four of its ports is the maximum the port it is plugged into can supply. For USB 3 ports on desktop computers, that is usually 900 ma (0.9 amps); for some laptops it may be only 150 ma (0.15 amps). So no, it will not supply anything even close to four amps on any of its ports, nor will it supply more than 0.9 amps on any one port when plugged into a normal USB 3 host port on a computer even if the other three of its ports are unused.

unknow. I cannot find specs that indicate amps available at the usb ports. I would suspect that 2.1 is the sum total available. That would be a lot of amps for a usb port. That would be around 25/26 watts (at 12 volts) You should determine the load of your plug-in before attempting to power it through this converter.(remember- Volts times amps equal watts) If you know any two of these you can determine the other.

It have 8 individual 9v port plus one 18v output, one strip to change polarity if needed, not sure of output amperage
